Shan et al. identified a nonsense mutation in the bovine Abhydrolase domain containing 16B gene ABHD16B (SNP rs468948776 AC_000170 g.54429815G>A) associated with male subfertility in Holstein cattle. The mutation causes a premature stop codon at amino acid position Glu 218, resulting in a truncation of 235 C-terminal amino acids. ABHD16B is involved in lipid biosynthesis in testis and is crucial for fertilization
